I heard of some people hatching eggs with a heating pad. My cousin had 4 eggs that was under a game hen for 4 days. The hen left the nest and eggs he candled and all 4 eggs are developing. He does not have a incubator. What he has is a medium tote with lid that he is thinking to cut a hole in lid and make a window covered by plastic he has one of those temp/humity readers He has a heating pad he placed the temp/humity reading in the heading pad. He also put in a tube of water and some sponges. He is waiting for the readings. My question is what should the temp and humidity be AND is it possible to do this for 17 days and the eggs still hatch?
